Francois Truffaut and Claude Chabrol dreamed up the story, a riff on Gun Crazy and homage to Bogart. It is celebrated for its technique but it is so much more. Jean-Luc Godard conducted an alchemical transformation with Raoul Coutard’s moving camera and jump cuts; the music by Martial Solal has a breezy quality that transports us there, to that very place, Paris, at that moment; the cars and shirts and hats make us dream of timeless style. Belmondo is insouciant and charismatic, Seberg disarming. The quality of charm is underrated in movies: that is what remains in this core episode of cinema, the ultimate cool. Essential.
